Application Agust 16, lmaserial160.4988181 4 claims. gems-181) i -My invention relates to concrete building structures, and has amongits objects and advantages the provision of an improved self -supporting form embodying adjustment for sizeand iiexibility as t`o` uneven ground contour to facilitate the construction of foundations for buildings and the like.

theform separated for the purpose of illustration;

`Figure 5 is a view similar toFigure 4 but illustrating the parts in their connected relationship;

Figure 6 is an end view bf the structure ofFigurel5; l Figure '7 is a `sectional detail'view illustrating a mount for a termite plate to be incorporated in the foundation;

Figure 8 is a face View of the structure of Figure 7;

Figure 9 is a sectional view through a portion of the foundation illustrating the termite plate anchored therein;

Figure 10 is a top plan view of a corner form unit; and l Figure 11 is a top plan view of a partition unit for disposition between the wall sections.

In the embodiment selected for illustration, the formlII) comprises spaced side walls I2 and I4.

`Both side walls are formed of sheet metal and each includes a base flange I6 perforated for the reception of anchor pins I8 which may be driven into the earth to make the form secure.

Wall I2 comprises sections 20 and 22 divided longitudinally and engaging edge to edge, as at 24. The upper section is bent to provide a horizontal flange 26 having an upstanding flange l 28. The lower section 22 is provided with an oifset 30 so as to give the concrete foundation suicient width along its base.

Wall I4 comprises an upper section 32, an intermediate section 34 and a base section 3.6. Sections 32 and 34 are divided horizontally and meet edge to edge as at`38. Section 34 includes a reladifferent positOllS for varying-the width of the foundation base, as: by shifting the section36 toward or away from the section 30. Sections 32 and 34 lare spaced from the sections 2li and 22 and are iixedly retained in such spacedrelationship by means of spacer tubes 48 having bolts 5 0 extended throughout. The horizontal ange 52l of the section 32 liesin a common plane `with the ange 26 and the flange 32 is provided with an upstanding flange 5 4 arranged in parallelism with the flange 2 8.

The flanges 28 and 54 function as rails for guid ing cars employed in conveying the concrete from the mixed to its place of dumping in the form, Such cars are provided with anged wheels. Thus the upper part of the form embodies a track function to facilitate movement of carsthere- 46 so that the section 36 may be adjusted to 55 Figure l illustrates the form I Il as being divided vertically into sections Y56, 58,60. and 62. Sections 56 and 58 are of the same vertical height, which height is somewhat greater .than the` sections 6U and 62. Sections `6I) Vand ,62 are mountedr on a ground level `6 4 higher. than the .ground level 66 on which the sections 56 and 58 are'mounted.

The number of sections of the same height will depend upon the length of the building foundation and the inclined nature of the ground formation. Ground levels 64 and 66 are dug to lie in horizontal planes.V All the sections terminate in a common horizontal plane at their tops, and inclination of the ground surface is compensated for through the employment of form walls of variable heights. This feature greatly facilitates the construction of foundations on inclined ground formation.

Figure 3illustrates the section 58 in cross section, which section is identical with the section of Figure 2, with the exception that wall plates 68 are inserted between the respective wall sections 20 and 22 and 32 and 34. The wall sections 20 and 32 of Figure 3 are provided with angles 'I0 iixedly secured thereto and overlapping edge mare gins of the plates 68. Angles 12 are secured to the respective plates 68 and overlap edge margins of the walls 22 and 34. Plates 68 represent the diiference in height between the sections 58 and 66. l

In Figure 4, the walls 20 and 22 are separated from their respective plates 68. To one end of the wall 20 is riveted a bar 'I4 having an offset 16 between which and the wall 20 is inserted one end of a bar 'i8 riveted to the plate 68. Bar 18 also includes an offset between which and the plate 68 is inserted one end of a bar 82 riveted to the wall 22. All the bars 14, 'I8 and 82 project beyond respective ends of the walls and the plate so as to have overlapping relationship with end margins of corresponding walls and plates which may be connected in end to end relationship. Openings 84 are provided in the Ibars 14, 78 and 82 for-the reception of the bolts 50. Offset 'I6 is designed for coaction with the bar 18 in cases where the plate 68 is inserted or With the bar 82 in cases where vthe form wall is of minimum height.

Figure 1U illustrates a corner form unit 86' which is identical in construction with the' adjoining sections with the exception of the bend therein. Figure 11 illustrates a partition unit 88' interposed between the Wall sections 90. Partition unit 88 is identical with thev wall sections 90 with the exception of the T-shapedv contour of Figure 11.

Figure 9 illustrates a termite plate 92 arranged at an acute angle to the outside` iacer 94 of the foundation 96. Plate 92 has a Wide edgemargin 98 embedded' in the foundation. 96 the margin 98. being provided with openings lll!) for anchoring purposes. Plate 92 originally lies nat against the inner face of the wall section 2l) with the edge' margin- 98 arranged at right angles to the plate; Margin 98 lies adjacent an angle 102 bolted at |04 tothe wall section 2D'. Clips lutv engage the lower edge margin ofthe plate 92 and arem'ade secure to the wall section 2li by nuts |08. Plate 92 is bent to its angular position. of Figure 9' after the concrete has set. The angular plate 92' extends completely about the building and. provides a barrier which prevents the termites from ascending thefoundation beyondthe plater The form is so contoured as to balance in an upright position. The base anges are pegged to the earth soas to restrain the form from accidental shifting. In addition, the form may be adjusted to provide foundations of' different tlrricknesses. y

Without further4 elaboration, the foregoing will so fully illustrate my inventiom that others may,

by applying current knowledge, readily adapt the same for use under various conditions of service.

I claim:

1. A concrete form comprising spaced vertical walls, means acting on the walls to hold the latter in predetermined spaced relationship, opposed outwardly and downwardly extending base formations in said walls flanges on the lower edges for supporting the form in an upright position, and outwardly and upwardly extending portions on the. upper edges of said walls to provide a track for awheeled concrete carrier.

2. The invention described in claim 1 wherein one of said walls is extending upwardly and is adjustably connected with its respective Ibase formation for adjusting either with respect to the other to vary the thickness of the form.

3. A concrete form comprising spaced vertical walls, each wall comprising upper and lower sec. tions, unanged iiller plates adapted for location between the sections in edge to edge relationship, reinforcing members for said sections and ller plates, means acting on the walls to hold the lat-- ter in predetermined spaced relationship, base formations in said walls for supporting the form in an upright position, andk an extended part on one base flangeA for adjusting the base formation in one wall laterally of that wall.

4. A concrete form comprising two units arranged end to end, means for connecting the two units in end to end relationship, each unit comprising spaced vertical walls, means acting on the w-alls to hold the latter in predetermined spaced relationship, 4base formations in said Walls for supporting the -form in an upright position, said walls being divided horizontally into sectionsand unflanged ller plates interposed` in edge contacting. relationship between the sections of one of said. units to locateV the base formations thereof beneath` the base. formations of the other unit, wherein said vertical walls are provided withoutwardly and upwardly extending. portions along their upper .edges to provide a trackfor a wheeled concrete carrier.
